Primate Conservation Current Lecture Primate Altruism: Altruism: Getting along with and helping others at the cost of one's own fitness and without any guaranteed help returned, although it often is. Why display altruistic behaviors when you can get put at risk? -group selection: having altruists in a group can help the group thrive. example, primates of various species all using various calls to alert each other to threats. - ken selection: since the goal of natural selection is to get as much of your genetic information into the next generation as possible, and since kin share genetic information with you, then helping them increases their fitness as well as your own. comes naturally, since in most groups primates are closely surrounded by kin. -reciprocal altruism is a system where you help others who help you in return. this requires knowing and keeping track of who has helped you, and coming in contact with that individual multiple times. - in humans, altruism goes further as the acts of altruism in humans are generally done with the recipient in mind, even if the person does not personally know the recipient (charities). Since primates do not do this generally, it is difficult to say if their acts of helping others is truly considered altruism. Primate Conservation -humans have been around for approximately 10,000 years. During that time, humans have expanded rapidly, and everywhere they expand, they modify the environments to fit their needs. However, since the human population has grown and expanded extremely quickly, environmental conservation is a very serious problem that needs to be handled with care. - it is a believed idea that the reason other homo species besides Homo sapiens are no longer around, is because Homo sapiens competed with them to extinction.
